I've had my Shark 2 weeks & I love it so far.  I
really like how I can get under my low sofas. I bought it for my hardwood floor thinking it only had fins, not brushes. I am hoping the brushes are soft enough not to scratch my floor. I do wish you could turn the brush roll off completely. It really finds the dust & dog hair! I use it for hard floors & area rugs. It is a bit pricey & I'm still getting used to the fact it doesn't stand up. So far so good, we will see how long it lasts!
